Rent, residents, age, household size, ownership and vacancy are Zensus 2022, aggregated from the 100-metre grid published by the Statistisches Bundesamt under Datenlizenz Deutschland 2.0. Germany does not publish postcode boundaries openly, so each grid cell is assigned to the nearest postal code centre and averages are weighted by cell population. Figures from the Regionalatlas of the federal and state statistical offices, Datenlizenz Deutschland 2.0. They describe the municipality this postal code falls in — Germany publishes by Gemeinde, not by Postleitzahl. Climate normals from the Deutscher Wetterdienst, 1991–2020.
